Unlike any gas extinguisher, Bonpet liquid does not have to fill up the whole room in order to extinguish the fire; just a thin layer of few millimeters above the burned surface is enough.
While decomposing endothermic-ally, Bonpet liquid absorbs 10 times more energy from the burning surface than gas would. Extinguishing a fire with a gas can cause re-ignition if the gas runs off too quickly.
